Torque multiplier and method of use

摘要

A torque multiplier apparatus includes an input pinion, a geared torque multiplier mechanism, and an input retainer. The input pinion and the input retainer include first and second identical connectors so that a detent stud can be positioned in either one of the first and second connectors, allowing the torque multiplier to be used for increased torque (and reduced speed) or for increased speed (and lesser torque). A related method includes engaging the driving tool with the first connector and the socket with the second connector to provide an increased torque on a socket to break loose a fastener, and flipping the torque multiplier so that the driving tool engages the second connector and the socket engages the first connector to provide an increased speed of torsional rotation to more quickly remove the fastener from the shaft. The detent stud is torsionally shearable, thus preventing over-stressing and damaging the tool.

主权项

1. A method comprising steps of:
providing a torque multiplier tool with first and second identical input/output connectors operatively connected by a torque multiplying mechanism, a driving tool, and a fastener-nut-engaging socket, the first and second connectors on the multiplier tool each defining identical square sockets and the tool further including a detent stud defining identical opposing square-shafted ends both shaped to selectively matingly engage the square sockets and to engage a square socket on the fastener-nut-engaging socket; the driving tool defining a second mating square-shafted end identical to the opposing square-shafted ends; engaging the square-shafted end of the driving tool with the square socket of the second connector while engaging detent stud between the square socket of the first connector and the square socket of the fastener-nut-engaging socket; engaging the fastener-nut-engaging socket on a fastener and operating the driving tool to provide an increased torque on the fastener-nut-engaging socket to break loose the fastener from a tightened condition; flipping the torque multiplier tool and repositioning the detent stud from the square socket of the first connector to the square socket of the second connector and engaging the driving tool with the square socket of the first connector so that the driving tool directly engages the torque multiplier tool and the fastener-nut-engaging socket engages the detent stud which is in the second connector; and operating the driving tool to provide an increased speed of torsional rotation to run the fastener along a fastener-engaged shaft to more quickly remove the fastener from the shaft.
